When a tree isuprooted,it might fall into some other trees on its way down,thus fallingonly partway over.Or it might crash all the way down to the forest floor.Either way,if its roots are pulled up from out of the ground as the treetopples over,then there’s usually a big hole,a pit left in the ground wherethe roots used to be.And there’s still a lot of soil attached to the roots,clinging to the roots.As that soil is eventually shed from the roots by rainand wind and the movement of squirrels climbing around,things like that.Um...as the soil is shed,it drops down and forms a little hill of dirt,a mound.
